Firefox in Ubuntu does not support Smart Card reader out box. In this tutorial, I used SCR3310 V2.0 as example. Reader
my other post regarding how to set up this reader in Ubuntu and enable pcscd service.
1. We need libopensc.so.3 file from OpenSC package
#Install opensc
sudo apt-get install opensc
2. Open Firefox, click "Open Menu" >>"Preferences">>"Advanced">>"Certificates" >>"Security Devices">>"Load"
in the "Load PKCS#11 Device" window, put
Module Name: PIV Card Reader (or any name as you wish)
Module filename: "/usr/lib/opensc-pkcs11.so"
3. Restart Firefox you should be able to see all your certificates on PIV card under "Certificates">>"Your Certificate" tab.
